Volvo Construction Equipment unveiled its prototype hybrid wheel loader known as the LX1 at the Xploration Forum in Eskilstuna, Sweden.

Volvo Construction Equipment (Volvo CE) reinforced that energy efficiency is at the top of the company’s agenda when it unveiled its prototype hybrid wheel loader – known as the LX1 – at the Xploration Forum in Eskilstuna, Sweden, on September 14th. The company gave customers, the international press, government representatives and academics an exclusive look at the electric hybrid machine, which can deliver up to a 50% improvement in fuel efficiency. On top of this, the LX1 also offers a significant reduction in emissions and noise pollution compared to its conventional counterparts.

The LX1 is a series hybrid that incorporates a driveline that consists of electric drive motors mounted at the wheels, electric hydraulics, an energy storage system, a significantly smaller diesel engine and new machine architecture. It’s this combination that enables the substantial gain in fuel efficiency. The prototype – which has 98% new parts and a fundamentally new machine design – is capable of doing the work of a wheel loader that’s one size larger. At this stage, the LX1 is part of a research project and it is not commercially available.

The Volvo Group defines electromobility as ‘commercial vehicles and machines that can utilize an electrical motor to propel or to perform the main purpose of the machine’. A hybrid is classified as a machine that uses more than one power source and captures and reuses energy that would otherwise be wasted. It is a prerequisite that the machine has the capability for energy storage to count as a true hybrid.

Volvo CE started its journey with electromobility and hybrid technology in 1998. The company has long-term plans to develop products and services for electromobility, including electric hybrids and electric sites. “Although we believe that there will be a major shift towards electric hybrid technology in the future, our customers, quite rightly, want improved efficiency now. We are delivering this through more conventional technologies and soft offers,” says Scott Young, electromobility program manager at Volvo CE. “This is because we need to meet customers’ immediate expectations in terms of total cost of ownership (TCO). A large part of TCO is energy cost, but other significant expenses include purchase price and maintenance. These aspects help drive our hybrid development plans. Therefore, before we launch a machine like the LX1, you can expect to see elements of this design incorporated into our products. This supports short and mid-term developments and requirements while the market continues to accept the technology, technology improves and the cost of new technologies decreases.”

Volvo CE has teamed up with its customer Waste Management – the largest environmental services and recycling company in North America – to field test the LX1. Waste Management, which owns one of the largest fleets of Volvo CE equipment in the world, is currently running a conventional machine to gather baseline data at two of its facilities in California. After the Xploration Forum, the LX1 will be shipped to the company so that it can carry out fuel efficiency and emission reduction tests at these sites.

“We see Volvo CE as a strategic partner,” says John Meese, senior director of heavy equipment at Waste Management. “We have one of the largest fleets of construction equipment in North America and want to use the best available technology to improve our operations and the service we deliver to customers. From the minute we were introduced to the LX1 we knew we wanted to work with Volvo CE to prove the concept in the real-world environments we operate in. We are anticipating excellent results when it comes to reducing the use of fossil fuels and lowering exhaust emissions. An additional benefit is the dramatic reduction in noise pollution.”

“Although it may be possible to realize fairly high levels of fuel savings and productivity gains in prototype form, when it comes to serial production you have to consider cost and ROI,” concludes Young. “Hybrid technologies are still a relatively expensive solution and adoption has been slow. This is because the benefit of current hybrid machines on the market isn’t significantly higher than conventional technologies, so it takes longer to achieve payback on your investment. However, the cost of energy storage systems like lithium ion batteries is steadily decreasing, along with other technology, so that’s starting to make hybrids more attractive financially. There are still opportunities to further optimize conventional technology – and these developments will compete with hybrid technology for some years. Although having said that, we are currently in a period of exponential technology growth and I believe this industry shift will move at a faster pace than others have in the past.”

Charleston County, South Carolina opened their compost facility in 1989. Back then, the concept was quite visionary and progressive - the idea of a municipality operating a compost site was still rather nascent. But for the first 20 years the outcome was moderate at best, as the operation mostly stockpiled green waste and let time do most of the work. That all changed dramatically in 2011 when they reached out to Darren Midlane of Harvest Quest. After applying Harvest Quest inoculants and committing to the MSAP (modified aerobic static pile) method, Charleston County's composting facility has transformed from the "armpit" of the landfill to a crown jewel of national waste management.
